To al? whom t may concern l Be itknovm that l, Jams ROBERT STEELE;

a citizen of the United States, and a resident of Owego, in the county of Tioga and State of, New York,have invented certain new j and usefuldmprovements in Anticreepers, p'ofkwhichthefollovving is a speciication. Thelobject'of my invention is tovprovide i a simple andspecia'liy; eiicientdeyice to prevent creepingorylongitudinal inpvement railroad rails.f y y the, 'drawing-illustrating a preferred embodiment o,i" y my I,novel enti-creeper l Figure l-isjarear elevation .ofthe anticreeper appliedto ae' ,ibeforeilocking the rail being shovviiingjsection, anda tie in A elevation, andthe yoke of ,the anti-creeper Fig. 2 is a viewsimilary to Fig. ll` -shovving the wedge driven home ,and locked by the coperation of the deorrnabletail 'with the opening of the yoke.

'l ig. 3 isa sectionon the line 3*,-3 of Fig. 293116.- v, I .r-

Fig. 4 isa perspective view of the Wedge. The device includes'a yoke l having suitable ends 2' andk 3 to take over the edges ot the rail base', and a transverse under-rail portion 4, the ,upper surface of which is separated from the bottom of tlIe'rail base and inclined in the direction of its length Yrelatively thereto. Within this space and yf'npon the vvedgavvay thus provided is a Wedge 5, v-ihich is driven transversely of the rail .to secure the anti-Creeper in lace. Itv will be understood that the device is applied to' and -removed from the ,rail laterally.- and that the yoke is constructed With sutlicient room between the hook ends and `loody to afford clearance forl this purpose,

Y v asvvell as to accommodate the wedge. As is customary, one end, in this instance the end 2 at'thel higherend of the Wedgeway, is more deeply hooked or undercut than the other, this being the end which is engaged lirst with its edge of the rail base when the device is tilted onto the rail. The wedge is materially shorter thanthe space included between the rail base at the top, the yoke body at the bottomand the hook-ends at `up and alon 'the sides,`and substantially shorter 'also than the Wedge-Way yvvhereon it travels. Theupper side ofthevvedgeds preferably substantially horizontal, and its= engagement with the yoke maybe rendered more secure and the driving operation facilitated by forming the lateral portions 6 of the Wedge so as to f project beyond the lines of the yoke and to Patenten oet. 3c, ier?.

lili

extend vertically down at the sides thereof.

Maniestly7 however, it is not necessary that both sides of the wedge project, and an extent of vertical overlap between the Wedge and yokeftvhich is qulte important to prevent relativeidisplacement transversefto the direction otdriving, may be secured by speciically different forms.

When the anti-Creeper is placed 'upon the rail andthe relativel short Wedge driven comes slightly sprung, bringi into play the elasticity oi'nthe material an securing fresilient binding action which is especia its We ge-way, the yoke bea ly' desirable in a device of this character. The 'i result of thisaction is not only. to cause the ends of the yoke to grip the rail basetenaeiously but to lock the Wedge against'retro- I grade movement through slight bowing or deflection of the Way upon. whichit ni'ust move.

The wedge may'4 lie additionally locke-d y against undesired release-by means of a daformable rod 7 fitting an opening 8 in the end 3 of the yoke and cogeratngl with the "rear end of the Wedge, torvvhich it may be v`secured; This openingend also the rod vo'r tail are inclined to thev wedge-way when the parts of the anti-creeper a'revlassembled in readiness for driving, as shqvlnlin Fig.' vl.

In the present instancethey are representedv as being horizontal, but obviously the hole might be inclined to the horizontal [as well as to the plane of the .wedgefWay,v that'is as shown in Fig. 2 the tailjbendsslightly .soesto hind with the opening, thereby producing'an eliective lool; :rendering it doubly impossible. for the wedge to Work beekjes `say the relative inclination could be greater ,if desired. lWhen the wedge 1S driven home,

the result of vibration andshocks dueto the f movement of, trains upon the rails.
